[visad] Issues with zero-values on flow mapping

Hello,

I visualize data from a finite element analysis with VisAD Tue Dec 23
13:47:46 CST 2008.

When I try to map the x-, y- and z-components of tensions to Display.Flow1X
... Display.Flow1Z,
those arrows are not painted correctly where all components equal to 0.0f .

This applies to 2D and 3D displays. Please see the attached screenshot.

What am I doing wrong ?
